Dating back to 1885, the newly added collections are of shape producer catalogs, which are the basis for much of the information found in AISC Design Guide 15, Rehabilitation and Retrofit Guide. Information includes data for discontinued wrought iron and steel shapes, a review of ASTM material standards since 1990, and information on enhancing structural systems.
